Hello! New Robo owner here - ack!

On May 1, my 12yo had saved enough money for a Robo, cage, etc. So we got one. A male, so they said (!). We felt bad that he was lonely, and for leaving his brother behind, so on May 3 we went back and got his "brother". Muffin and Puffin, the Uffin Brothers.
On May 23, at 10:15 pm, my 12yo came running into the living room and said he'd heard a lot of squeaking - we had two new babies! Obviously, we have Mr. and Mrs. Uffin now. So the babies did well, were named Biscuit and Crescent, and are just the cutest little things. According to what we read, we had to wait 3 weeks to clean the cage re the babies, and we left, um, BOTH adults in there - they were awfully cute together, taking care of the babies.
Apparently there is no waiting period for sex between hamsters after a birth. Who knew. Ha.
So, on June 10 we bought a second cage, etc., and the next day moved Muffin (dad) to his new digs. On June 12, oops - MORE BABIES! ACK! There are 3-4, but I guess I'm wondering what to do now. Mom keeps moving the babies up to the petting zone - no way they're getting there by themselves - then moves them back down after half a day or so. Altho, at this point, they've mostly stopped moving....
I'm thinking she's had E-nough, but might be nursing one or two of the others.
Thoughts?
